Title: Weighing apparatus
Inventor: CORY WILLIAM EUGENE
IPC: G01G3/147
Filed: 1969-03-20
Abstract: 1,221,743. Weighing apparatus. SANDS MEASUREMENT CORP. 20 March, 1969, No. 14665/69. Heading G4H. In weighing apparatus, extraneous perturbations are eliminated by first storing the maximum and minimum signals derived from load sensing strain gauges with no load applied and calculating their average to give a base signal, then storing the maximum and minimum signals derived with a load, the average of these signals being calculated and the base signal subtracted from it to give the actual load. As described, a wheel of a train to be weighed trips a switch 93 (Fig. 8) before it reaches the weigh rail and for a fixed time interval after this an analogue/digital converter 150 digitizes the output of bridge network 105a and after each digitization compares the newly digitized data with the previous maximum and minimum data stored in shift registers 154, 155, replacing the stored data by the new data only if it is larger or smaller, respectively, so that after a time Tt the highest and lowest signals received are stored. An arithmetic section 157 then calculates ¢(max.-min. + 2 min.) that is ¢(max.+min.) and stores this base value in base register 163. When the wheel reaches the scale a further switch 85 is operated so that the maximum and minimum signals with the weigh rail loaded are derived this process being terminated by the wheel tripping a further switch 85a. The arithmetic section then calculates ¢(max.- min. + 2(min.-base)). This is fed serially to an output register 164 connected in parallel to counter 165, the counter controlling a printer or recorder. In a modification (Fig. 16, not shown) the arithmetic section first calculates max. - ¢(max.-min.) to give the base signal and then (max. - base) - ¢(max.- min.) to give the actual load.

Title: Improvements in or relating to the Grinding and/or Polishing of Glass, and Apparatus therefor.
IPC: B24B7/24
Filed: 1917-10-10
Abstract: 120,594. Pilkington Bros., and Slocombe. F. E. Oct. 10, 1917. Flat extended surfaces, surfacing and polishing; disk apparatus; wheels; supplying abrading-materials; vacuum work-holders. - Apparatus for grinding or polishing plate glass comprises two disks mounted on two horizontal shafts, which are out of line but approximately parallel, one at least of the shafts being driven and one or both of the disks being provided with sucker devices for securing glass thereto. As shown in Fig. 1, the apparatus comprises a disk 1 fitted with suckers and mounted on a shaft 3 driven by a motor 11 and gearing 9, 10. The second disk 2 is mounted on a shaft 4 supported in bearings 6, 14 on a frame 8, which is adjustable along guides 15, 16 by means of a screw 20 and may be given a slight angular adjustment by set-screws 26 with heads bearing against ribs 24 on the fixed under-frame. The disk 1 is forced towards the disk 2 by fluid pressure admitted to a cylinder 13, and the pressure may be transferred to the opposite side of the piston periodically by a valve 31 actuated by a cam 30 on a shaft geared to the shaft 3. At the separation of the disks 1, 2, a valve controlling the supply of abrasive material is actuated. The cam 30 is preferably shaped to give a rapid withdrawal of the disk 1 and a gradual return. The axial movement may alternatively be effected by a cam acting directly on the shaft 3. The exhaust passage for actuating the suckers on the disk 1 passes axially along the shaft 3 to a pipe leading to a pump. Abrasive material may be supplied to the disk 2 by a hole through its shaft, or by a pipe 32 leading to an undercut ring 33 at the back of the disk. It may be supplied also to the face of the disk by a spreading-plate 27. The disk 2 also may be provided with suckers for securing waste or other glass thereto, so that the glass surfaces may grind each other by means of abrasive supplied between them. The abrasive may be supplied through holes in the disks, the glass being arranged to leave gaps over the holes. Glass plates may be transferred to or from the machine by dummy disks fitted with suckers and with side cramps for securing them to the machine disks during the release of one set of suckers and the application of another set. Two dummy disks may be used for reversing the glass sheets. The suckers on all the disks are arranged in the same relative positions to facilitate transference. In the arrangement shown in Fig. 2, a pair of disks 34, 35 are mounted on a shaft 36 running in a spherically-seated bearing 37 placed between two driven disks 1, 2. All the disks may carry suckers, those on the disks 34, 35 being exhausted by a pump and motor attached to the back of one of the disks, and current being supplied by slip rings on the shaft 36. Pressure cylinders similar to the cylinder 13, Fig. 1, may be arranged for each of the disks 1, 2, both cylinders being controlled by the same set of valves.

Title: Improvements in and relating to Digital Computer Systems
IPC: G06F9/26
Filed: 1968-03-27
Abstract: 1,176,894. Computer systems; input-output control. BURROUGHS CORP. 27 March, 1968 [27 March, 1967], No. 14695/68. Heading G4A. In a digital computer system in which a plurality of terminal input-output units each connected to a respective data communication line are selectively connected through control means to one of a plurality of input-output channels communicating with a control memory, selection of a terminal unit for transmission of data causes corresponding function signals from a function matrix to be applied to the control means. The function signals indicate the type of terminal unit selected and enable terminal units of different types to be easily connected to the system. As shown (Fig. 4) the multi-line control unit 23 of the time sharing computer system described in Specification 1,172,494, is modified by the addition for a decoder 100, function matrix 101 and control code matrix 102. Each of the plurality of data communication lines 28 from respective input-output terminals 61 is connected to the multi-line control unit by respective line adapter 58 (shown as a single block for simplicity) which provides a common interface between the different terminal units 61 and the unit 23. When a particular adapter is selected for transmission of data by a scanner 67, identification signals indicating the type of terminal unit concerned are issued by the adapter on a 5 line information bus 104 (Fig. 5, not shown) and passed to a decoder 100 which energizes a corresponding one of 32 output lines 105 connected in groups of eight to 4 integrated circuit cards which together comprise the function matrix 101 (Fig. 6, not shown). Output lines 106 from the matrix 101 carry signals identifying the type of terminal unit 61 concerned to control circuitry 71. These signals may for example indicate data transmission order, character size, parity type, whether transmission is synchronous or asynchronous, line type and whether or not a start code is utilized. The cards forming the matrix 101 are interchangeable and/or modifyable to adapt the system to different terminal units. Output lines 107 from the matrix 101 carry signals which select one card of a plurality (e.g. 8) of integrated circuit cards forming the code control matrix 102 (Fig. 7, not shown). Signals representing characters temporarily held in register 78 during transmission are passed in parallel to the card of the matrix 102 and a signal is issued on function lines 109 connected to control circuitry 31 whenever a control code character is detected thereby. The cards of matrix 102 are interchangeable to enable the system to accept different code formats. The cards of matrices 101 and 102 may comprise diode matrices.

Filed: 1933-05-24
Abstract: 404,861. Arc-rupturing in switches. WESTINGHOUSE ELECTRIC AND MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Ellis, J. D.; 310, George Street, Turtle Creek, and Armstrong, G. C.; 33, Sumner Avenue, Wilkinsburg, both in Pennsylvania, U.S.A.) May 24, 1933, No. 14951. Convention date, May 25, 1932. [Class 38 (v).] Electromagnetic switches ; contacts.-The arc chute 31 of a switch is so mounted that it may be moved to expose the contacts 15, 16 and to prevent their closing. The chute is pivoted to the ends 41, 42 of a U-member 40 which is adjustably mounted by means of a screw 43 to an arm 22 to which is screwed at 44 the fixed contact 16. The movable contact 15 has a ridge-and-groove pivotal connection 21 with the carrier 17 mounted on the armature 12 of the operating magnet 11. A frusto-conical enclosure 23 houses a spring 20 serving to bias the contact 15 against its carrier and provide contact-pressure with 16. When the chute is rotated clockwise about 41, 42 to expose the contacts, a bridge 37 interconnecting the limbs of the chute engages a depression 45 in the contact 15 and by the arrangement of the pivots holds the contacts open against the weak attractive force on the armature, the latter force however being utilized for assisting to restore the chute to its operative position when the line of action of the closing force has passed below the pivots 41, 42. The chute pivots however may be arranged so that the force always tends to restore it to the operative position, but the contacts cannot be closed until they are adequately housed by the chute. The inner walls of the chute are ribbed to facilitate cooling and extinction of the arc, and are cut away at 34 to permit access to screw 44 when the chute is raised. In Fig. 5, the coil 11 is also de-energized by the displacement of the chute removing a spring blade 55 from normal contacting engagement with the arm 22. A modified pivot is also fitted, comprising a bracket 51 fastened by the screw 44 and having holes for bearing pins, as 52, on the chute. In another form, Fig. 7 (not shown), a sickle-shaped arm is urged by a spring into an obstructing position when the chute is raised, or even removed.
